If your iPhone has been disabled, it is completely locked down. The only way you'll be able to use it again is by restoring it using iTunes or iCloud. If you have a backup, you'll be able to recover your data, but this process will delete everything that is stored on the iPhone. Except for the following four ways, there is no other way to unlock a disabled iPhone.
Connect your iPhone to the computer with via a USB cable that your iPhone has trusted.
Launch iTunes. If you've synced your iPhone with iTunes, then no "enter password" is required.
iTunes will automatically sync your iPhone and create a backup file. If it doesn't, you should sync your iTunes and create a backup file manually by clicking "Back up Now" in the Summary window.
In the Summary window, you can see the option "Restore iPhone". Click it to reset your iPhone. Once the reset process is complete, you'll be taken through the iPod's initial setup process.
Select "Restore from iTunes backup" during the setup process. This will load the backup that you created so that all of your data is restored.
